Argsort

Argsort

Usage

torch_argsort(self, dim = -1L, descending = FALSE)

Arguments

self

(Tensor) the input tensor.

dim

(int, optional) the dimension to sort along

descending

(bool, optional) controls the sorting order (ascending or descending)

argsort(input, dim=-1, descending=False) -> LongTensor

Returns the indices that sort a tensor along a given dimension in ascending order by value.

This is the second value returned by torch_sort. See its documentation for the exact semantics of this method.

Examples

if (torch_is_installed()) {

a = torch_randn(c(4, 4))
a
torch_argsort(a, dim=1)
}
